Summary: The study utilized a Bayesian hierarchical species distribution modeling approach to analyze small-scale fishery data in Chwaka Bay, Zanzibar, revealing that the spatial distribution of three species is influenced by factors such as temperature, depth, and seagrass cover. Comparing the results to ecological studies showed that this method can predict the distribution of analyzed species reasonably well.

Summary: This study investigated the trends in fishing effort and catch per unit effort of small-scale marine fisheries in the Mozambique Channel region in East Africa from 1950 to 2016. The study found that with an increase in fishing effort, there was a 91% decline in overall catch per unit effort, indicating a potential risk of overexploitation in small-scale fisheries.

Summary: The Socotra Archipelago in Yemen heavily relies on small-scale fishing, but the reporting of fisheries catches has been incomplete. This study reconstructs the total catches and fishing effort in the region from 1950 to 2019, finding that the officially reported catch accounts for only 20% of the total reconstructed catch. The findings suggest overexploitation of resources and highlight the importance of sustainable management for the fish stocks in the Socotra Archipelago.

Summary: Research on small-scale fisheries (SSFs) has shown that ecological studies are mainly focused on marine fisheries in Latin America, while inland and Asian fisheries are understudied. There is more coverage on bony fish and invertebrates compared to endangered cartilaginous fishes. Recent studies have shifted focus towards human dimensions and ecosystem ecology, moving away from a previous emphasis on population ecology.

Summary: Coastal fisheries provide livelihoods for millions globally, but are often poorly documented, particularly in developing regions. Data scarcity hinders the effectiveness of spatial tools for fisheries management. Therefore, innovative and cost-effective approaches are needed to monitor activities and inform sustainable management of fisheries and marine ecosystems.

Summary: Small-scale fisheries (SSF) represent a significant portion of the global and EU fleet. Mapping fishing operations is crucial for spatial planning and sustainability. Using high resolution data, we developed a procedure to categorize fishing boat behavior and evaluate the effectiveness of different classification methods.

Summary: The substantial increase in poaching within the fisheries' management areas in central Chile is driven by a combination of socio-economic factors. The study found that socio-economic factors and environmental variables play a significant role in poaching activities in the area. An integrated ecological and socio-economic approach can offer solutions to the unsustainable exploitation of marine resources.

Summary: Understanding fishing effort allocation is crucial for spatial management planning in fisheries, particularly in small-scale fisheries with multi-specific contexts. Random Walk models prove to be useful for modeling small-scale fleets operating in southeast Mexico, with the Composite Correlated Model identified as the most suitable model for this fleet. Further studies should consider increasing the number of fishing trips and conducting specific studies by gear and fishing method, along with applying relative and absolute fit tests to compare the performance of RW models.

Summary: This study examined small-scale fisheries data from 27 points in Brazil's northeastern region over 3 years using Benford analysis. The results showed that 20% of the fish landing data were highly inaccurate, especially from non-motorized canoes. Data from harbors in remote locations, particularly monthly catch values reported by several boats, were of poorer quality. Monthly data was found to be less accessible through this method compared to daily data.

Summary: Monitoring the use of anchored fish aggregating devices (AFADs) is crucial for effective fisheries management, although detecting their use presents a significant challenge in Indonesia. By equipping tracking devices on handline fishing vessels and applying spatial modeling approaches, it was possible to detect AFAD usage and fish catch success effectively.

Summary: Mangrove habitats play a crucial role in the fishing ecosystem, but lack of data on small-scale fishing may impact sustainability. This study examines the combination of different data collection methods and the use of published data for analysis of spatial dynamics. Results show that catch distance affects crab size, and incorporating GPS tracking into participatory mapping can improve geographical precision and access more information.

Summary: The study suggests that maintaining the level of shrimp catches can be achieved by controlling bottom trawling activities without compromising ecosystem structure. Closing the fishing season may lead to significant losses in catches of high market-value shrimp species, while decreasing primary production can have negative impacts on biomass, catch, and biodiversity indicators.

Summary: Small-scale fishery plays a significant role in the Mediterranean fleet, but its evaluation is challenging due to the scattered fishing effort. This study focuses on analyzing the characteristics of small-scale fishery in Corsica, an area with low fishing pressure. The study identifies different fishing techniques, species composition, and factors affecting catch per unit effort. The findings provide valuable knowledge for managing artisanal fishing in the Mediterranean.

Summary: The study revealed that climate conditions have a significant impact on the potential biomass of Gulf corvina, especially on the growth and survivorship of juveniles. Differences in growth responses to climate factors between juveniles and adults resulted in distinct growth relationships between the two life stages.

Summary: The future of the global ocean economy is envisioned as advancing towards a 'blue economy' which emphasizes socially equitable, environmentally sustainable, and economically viable ocean industries. Differences in outlook on the capacity for establishing a blue economy exist, with key factors including national stability, corruption, and infrastructure. Policymakers must engage researchers and stakeholders to ensure evidence-based, collaborative planning that prioritizes local benefits and aligns with social, environmental, and economic goals.

Summary: Climatic oscillations during the Pleistocene, particularly the Last Interglacial period, led to significant changes in global sea level and the spatial distribution of marine and terrestrial ecosystems. The study provides evidence of an extant, inland mangrove ecosystem as a relict of the Last Interglacial period, demonstrating the long-lasting impact of sea level changes on tropical landscapes and species ranges.

Summary: This study constructs an open-source, standardized, and reproducible workflow to monitor the extent of coastal and marine habitats in protected areas and other conservation measures. The indexes calculated by this workflow can help identify areas with opportunities for expanding protected areas, areas with the greatest contribution to global habitat protection, and areas with the potential to contribute globally to habitat protection.

Summary: Estimating the long-term sedimentary carbon sinks of mangroves and other blue carbon ecosystems is important for coastal research and conservation. This study assessed the limits of mangrove sedimentary carbon storage by sampling sediments in diverse mangrove environments. The results demonstrated that sediment depth largely explained the variation in carbon stock across the areas studied.

Summary: This study analyzed the effects of core sample selection and bulk density estimation methods on carbon storage estimates in sediments. The results showed that the choice of core sample did not have a significant impact on carbon density estimates. Estimating carbon density using carbon content as a predictor was highly precise, especially in sediments high in organic matter. However, using estimated bulk density for peaty sediments may lead to imprecise results.

Summary: Marine Protected Areas (MPAs) that ban fishing can restore marine life and replenish nearby fisheries. The implementation of the largest fully protected MPA in North America did not lead to a decrease in catches or a displacement of fishing effort to unprotected areas. Our findings support the idea that well-designed MPAs can benefit marine ecosystems and the fisheries they support.
